Advanced Methods in Surface Physics

Class at Faculty of Mathematics and Physics |
NEVF108

Syllabus

1) Quantitative analysis of chemical composition by photoelectron spectroscopy (PES), valence band PES. Wave vector of crystal states, of the photoexcited electron and of the electron outside the crystal.

Free electron final state model. Band structure determination for normal emission and variable photon energy.

Synchrotron radiation PES. Angle resolved PES of the valence band states, ARUPS.

Investigation of local structure by photoelectron diffraction, angle resolved photoelectron spectroscopy (PES) of core levels. Experimental band structures of two-dimensional systems.

Constant energy and Fermi surface scans. Spin resolved PES of magnetic crystals, majority and minority bands.

Inverse PES. Charge-excitation final states: Satellites, resonance PES.

X-ray absorption spectroscopy (XAS), NEXAFS-XANES, EXAFS. Hard x-ray PES - HAXPES. 2) Limitations of kinematical theory of electron diffraction, dynamical theory of electron diffraction on the surface of solids, application of dynamic theory in LEED and RHEED. 3) Application of electron spectroscopy and diffraction in surface science.
